Logarithmic Function with Vertical Asymtote at X=-6, Y Intercept=5

AI Thread Summary
To find the logarithmic function with a vertical asymptote at x = -6 and a y-intercept of 5, the function can be expressed as y = A log(x + 6). The value of B is determined to be 6, as it shifts the function to the left. To find A, the equation 5 = A log(6) is used, leading to A being approximately 6.4254 for base 10 logarithms or 2.7906 for natural logarithms. This establishes the complete logarithmic function based on the given conditions.

what will be the logarithmic function with a vertical asymtote at X = -6 that has the intercept Y = 5

I know the denominator will be x+6 to get vertical asymtote, but don't know how to get Log Function ??

There is no denominator. What does a log function look like ?

You log function will be of the form,

y = Alog(X+B)

Now you have to figure out values for A and B.

thanks for help, can you explain it in more details..I didn't understand the above function.

Regards

so its going to be something like L(x) : ( | X+6 |, sqrt 6 ) :rolleyes:
 
It will be,

y = Alog((x+6)

so you got the B correct.

There is a y-intecept of 5, so

5 = Alog(0+6)

What is A ?

A is 5:frown:
 
Nope.

5 = A.log(0+6)
A = 5/log(6)
A = 6.4254 (if taking logs to the base 10)
A = 2.7906 (if taking logs to the base e)
